The AN/APG-81 is an Active Electronically Scanned Array (AESA) designed by Northrop Grumman Electronic Systems for the F-35 Lightning II.The Joint Strike Fighter AN/APG-81 AESA radar is a result of the US government's competition for the world's largest AESA acquisition contract. Westinghouse Electronic Systems (acquired by Northrop Grumman in 1996) and Hughes Aircraft (acquired by Raytheon in 1997) received contracts for the development of the Multifunction Integrated RF System/Multifunction Array (MIRFS/MFA) in February 1996.[1] Lockheed Martin and Northrop Grumman were selected as the winners of the Joint Strike Fighter competition; The System Development and Demonstration (SDD) contract was announced on 26 October 2001.The AN/APG-81 is a successor radar to the F-22's AN/APG-77. Over 3,000 AN/APG-81 AESA radars are expected to be ordered for the F-35, with production to run beyond 2035, and including large quantities of international orders. As of August 2007, 8 APG-81s have already been produced and delivered. The first three blocks of radar software have been developed, flight tested, and delivered ahead of schedule by the Northrop Grumman Corporation. Capabilities of the AN/APG-81 include the AN/APG-77's air-to-air modes plus advanced air-to-ground modes including high resolution mapping, multiple ground moving target detection and track, combat identification, electronic warfare, and ultra high bandwidth communications. The current F-22 production radar is the APG-77v1, which draws heavily on APG-81 hardware and software for its advanced air-to-ground capabilities.[2]In August 2005, the APG-81 radar was flown for the first time aboard Northrop Grumman's BAC 1-11 airborne laboratory. Since then, the radar system has accumulated over 300 flight hours, maturing all five blocks of software. The first radar flight on Lockheed Martin's CATBird avionics test bed aircraft took place in November 2008. Announced on 6/22/10: The radar met and exceeded its performance objectives successfully tracking long-range targets as part of the first mission systems test flights of the F-35 Lightning II BF-4 aircraft.[3]The AN/APG-81 team won the 2010 David Packard Excellence in Acquisition Award for performance against jammers.

The Lockheed Martin Sniper Advanced Targeting Pod (ATP), designated AN/AAQ-33 in U.S. Military Service, provides positive target identification, autonomous tracking, coordinate generation, and precise weapons guidance from extended standoff ranges. The Sniper ATP is used on the F-15E Strike Eagle, F-16 Fighting Falcon, A-10 Thunderbolt II aircraft, B-1 (Rod Pod), UK Harrier GR9,.[1] and Canadian CF-18 Hornet. [2] The Sniper ATP is in service with Norway, Oman, Poland, Singapore, Canada, Belgium, Turkey, Saudi Arabia[3] and the UK MoD.[4][5] In July 2007, Sniper ATP was acquired by Pakistan, making it the tenth country in the world to be in possession of the Sniper pod.[6] The Sniper ATP contains a laser designator and tracker for guiding laser-guided bombs. The pod also features a third-generation FLIR receiver and a CCD television camera. FLIR allows observation and tracking in low light / no light situations, while the CCD camera allows the same functions during day time operations.A team of Lockheed Martin UK, BAE Systems and SELEX Galileo (formerly Selex S&AS) has successfully demonstrated and flown a Sniper ATP on board a Tornado GR4 combat aircraft.The U.S. Air Force initial seven-year contract for Sniper ATP has potential value in excess of $843 million. The Sniper ATP has delivered over 125 pods and the U.S. Air Force plans to procure at least 522 Sniper ATPs.PANTERA is the export equivalent to the Lockheed Martin Sniper Extended Range (XR) targeting pod.

Multifunction Advanced Data Link (MADL) is a future data waveform to provide secure data-linking technology between stealth aircraft. It began as a method to coordinate between F-35 aircraft (the Joint Strike Fighter), but HQ Air Combat Command wants to expand the capabiltiy to coordinate future USAF strike forces of all AF stealth aircraft, including the B-2, F-22, and unmanned systems. MADL is expected to provide needed throughput, latency, frequency-hopping and anti-jamming capability with phased Array Antenna Assemblies (AAAs) that send and receive tightly directed radio signals.[1]The Office of the Undersecretary of Defense for Acquisition, Technology and Logistics directed the Air Force and Navy to integrate MADL among the F-22, F-35 and B-2, to one another and to the rest of network.

The FA-70 need not be physically pointing at its target for weapons to be successful. This is possible because of sensors that can track and target a nearby aircraft from any orientation, provide the information to the pilot through his helmet (and therefore visible no matter which way they are looking), and provide the seeker-head of a missile with sufficient information. Recent missile types provide a much greater ability to pursue a target regardless of the launch orientation, called "High Off-Boresight" capability, although the speed and direction in which the munition is launched must physically speaking nonetheless affect the chance of success. Sensors use combined radio frequency and infra red (SAIRST) to continually track nearby aircraft while the pilot's helmet-mounted display system (HMDS) displays and selects targets. The helmet system replaces the display suite-mounted head-up display used in earlier fighters.The FA-70's systems provide the edge in the "observe, orient, decide, and act" OODA loop; stealth and advanced sensors aid in observation (while being difficult to observe), automated target tracking helps in orientation, sensor fusion simplifies decision making, and the aircraft's controls allow action against targets without having to look away from them.
